Checksum, steering angle, and steering torque sensor for Opel Astra K

Hello everyone,

Does anyone know the formulas for calculating the checksums in the data field for the two sensors?

Identifiers, messages, and signals:

0x1E5 PPEI_Steering_Wheel_Angle::StrAngSnsChksm

0x152 StrTrqCmd_A_HS::EPSCmdChksum

0x154 StrTrqCmd_B_HS::EPSCmdChksum_154

Sure, here is the translation of the text from German to English:

(The last two are probably the same)

Regards,
Eddie.
